ETS
Enhanced Transmission Selection (ETS) is defined in the IEEE 802.1Qaz standard (IEEE, 2011). ETS
supports allocation of bandwidth amongst traffic classes. It then allows for sharing of bandwidth when
a particular traffic class doesn’t fully utilize the allocated bandwidth. The management of the
bandwidth allocations is done with bandwidth-allocation priorities which coexist with strict priorities
(IEEE, 2011).
IOM
IO module (IOM) refers to the modules on the rear of the Dell PowerEdge M1000e chassis that will
receive and transmit I/O (Ethernet, FC, Infiniband, etc) from the blade servers. The Dell Force10 MXL
switch is as an IOM for the M1000e blade server chassis.
NPIV
N-port identifier virtualization which enables multiple N-port fabric logins at the same time on the
same physical FC link (Cisco Systems, Inc., 2011).This term is in reference to the Cisco Nexus 5000
series switches implementation of NPIV. NPIV must be enabled to share multiple logins across a single
port/link or a port-channel/multiple-line link.
NPV
N-port virtualizer is a FC aggregation method which passes traffic through to end devices, while
eliminating the need to use a domain ID for this device (Cisco Systems, Inc., 2011). This term is also in
reference to configuration settings on the Cisco Nexus 5000 series switches.
VSAN
Virtual SAN is a logical partitioning of physical connections to provide for fabric or SAN separation.
VSAN is a term that is particular to the Cisco Nexus series switches.
